This study explores the biological control of soft rot disease of Ziziphus jujube to reduce the loss caused by soft rot disease of Z. jujuba, and minimize pesticide residues. The fermentation medium of the highest rates of antibacterial Streptomyces rimosu CN124 for Btryosphaeria dothidea was selected using single-factor test combined with the evenness test through the regression analysis. The result showed that the optimum medium was starch 11.67%, corn flour 2.69%, (NH_4)_2SO_4 0.22%, CaCO3 0% and NaCl 0.03%.
